Thanks Chris! Can I ask you what you think an appropriate number of problems to answer in a 5 minute time span would be? You said over 100 problems, how many is that?
Also, for your timed drills, do you use just a blank of the superspeed, or do you pull from other sources for mixed facts as well so that they aren't accustomed to seeing it the same way? I was going to pull from other sources to do my timed drills.
Last year, our "school goal" was to be able to answer 100 facts in 6 minutes with 95% accuracy. Yesterday I did 122 X facts in 7 minutes, and a handful passed with 95 or higher, however it was only our first time.
In the past, we've also went through one fact at a time, for example timed drill on 6s, then when they passed that they moved on to 7s, then 8s, etc... I hated this because I had a full class with kids on all different things and it was a pain to keep up with and manage. I like using superspeed because it throws everything together, and I'm doing my timed drills that way. My logic to explain this is that we don't teach the ABCs in sequential, why should we have to teach/learn X facts in order?
